Reparation is a Christian theological concept closely connected with those of atonement and satisfaction. In ascetical theology, reparation is the making of amends for insults given to God through sin, either one's own or another's. The response of man is to be reparation through adoration, prayer, and sacrifice. In Roman Catholic tradition, an act of reparation is a prayer or devotion with the intent to expiate the "sins of others", e.g. for the repair of the sin of blasphemy, the sufferings of Jesus Christ or as Acts of Reparation to the Virgin Mary.

The Passion is the short final period before the death of Jesus, described in the four canonical gospels. It is commemorated in Christianity every year during Holy Week.
